Description

Technical Field

[0001] This utility model relates to the technical field of vehicle anti-pinch devices, and in particular to an active anti-pinch system for electric vehicle doors. Background Technology

[0002] With the rapid development of China's automotive industry, both traditional gasoline-powered vehicles and new energy vehicles are becoming increasingly intelligent. Electric suction doors and electric doors are gradually becoming standard or optional features on cars, and the "anti-pinch" issue of car doors is becoming an important indicator for more and more people to evaluate car safety.

[0003] Existing anti-pinch solutions for electric door or electric suction door problems are typically passive. These mechanisms rely on sensors to detect the trapped object, such as a physical item or the user's hand. The electric door system only stops closing or reverses slightly when the pinching force reaches 80N-100N. However, this passive anti-pinch method has limitations in practical applications. First, the trapped object may already be damaged before the pinching force reaches the set value. Second, sensitive areas like fingers may still suffer minor to moderate injury even after the pinching force is triggered. Furthermore, the reaction speed and sensitivity of the anti-pinch system are limited by the sensor's detection capabilities and control algorithms, resulting in less than ideal anti-pinch performance in certain situations, severely impacting user experience and safety.

[0004] Therefore, there is an urgent need for an active anti-pinch system for electric vehicle doors to solve the above problems. Utility Model Content

[0031] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] like Figures 1 to 4As shown, this embodiment provides an active anti-pinch system for electric doors. The system includes an anti-pinch detection device 1 and a controller 3. The anti-pinch detection device 1 is installed on the door. When the door is not closed, a detection area is formed between the door and the vehicle body assembly 2. The anti-pinch detection device 1 detects and determines whether an object exists in the detection area. The controller 3 controls the opening and closing of the door and is communicatively connected to the anti-pinch detection device 1. With this configuration, during the electric / manual closing process, the anti-pinch detection device 1 continuously detects and determines whether an object exists in the detection area. If no abnormality is found, the door closes normally. If the anti-pinch detection device 1 detects an object, it continues to transmit feedback to the controller 3, which then controls the electric door to stop closing, achieving active anti-pinch protection. This improves the overall safety and reliability of the electric door and enhances the user experience.

[0033] It should be noted that, in order to avoid false triggering, the non-pinch area within the door frame of vehicle assembly 2 is pre-marked as an undetectable area. This avoids the technical loophole that prevents the electric door from closing when someone is inside the vehicle. Furthermore, this active anti-pinch system for electric doors can be widely applied to electric side-opening doors, electric sliding doors, electric swing doors / electric tilting doors, electric suction doors, and other door systems equipped with electric suction locks.

[0034] Optionally, the vehicle door includes a door panel assembly 4 and a door sheet metal assembly 5. The door panel assembly 4 is installed on the inside of the door sheet metal assembly 5, and the anti-pinch detection device 1 is installed inside the door panel assembly 4. This arrangement, by embedding the anti-pinch detection device 1 within the door panel assembly 4, neither affects its function nor poses a signal jamming risk, and it is also protected from damage by foreign objects, thus extending its service life.

[0035] In this embodiment, to improve the stability and safety of the structural connection between the door and the body assembly 2, the electric door active anti-pinch system further includes a first hinge 6 and a second hinge 7. The first hinge 6 and the second hinge 7 are spaced apart vertically. One side of the first hinge 6 is mounted to the door sheet metal assembly 5, and the other side of the first hinge 6 is mounted to the body assembly 2. One side of the second hinge 7 is mounted to the door sheet metal assembly 5, and the other side of the second hinge 7 is mounted to the body assembly 2. With this arrangement, the pivot structure of the first hinge 6 and the second hinge 7 can ensure the stability of the door's opening and closing trajectory, avoiding interference with the body assembly 2.

[0036] Optionally, the active anti-pinch system for the electric door also includes an electric limiter 8. One side of the electric limiter 8 is mounted on the door sheet metal assembly 5, and the other side is mounted on the body assembly 2. The controller 3 is communicatively connected to the electric limiter 8, and the electric limiter 8 is used to control the range of motion of the door. With this configuration, the controller 3 can electrically assist the door in opening or closing to any position around the pivots of the first hinge 6 and the second hinge 7 via the electric limiter 8, all the way to the fully open or fully closed position. The entire process is smooth, without jamming or abnormal noise, and the door can be suspended in any position.

[0037] Optionally, in order to enable the automatic and gentle closing of the door and enhance the user's operational convenience, the electric door active anti-pinch system also includes an electric suction lock assembly 9. The electric suction lock assembly 9 is installed on the door sheet metal assembly 5, and the electric suction lock assembly 9 can drive the door to move towards the body assembly 2 so that the door and the body assembly 2 are closed and locked.

[0038] Optionally, in order to prevent accidental collisions when the door is opened and improve its safety performance, the electric door active anti-pinch system also includes a millimeter-wave radar 10, which is installed on the lower edge of the door sheet metal assembly 5 and is communicatively connected to the controller 3.

[0039] Optionally, the anti-pinch detection device 1 can be a millimeter-wave radar 10 or a camera module. In practical applications, the presence of an object in the detection area can be determined based on the radar distance signal or camera detection feedback. Of course, in other embodiments, the anti-pinch detection device 1 can also be configured as any foreign object detection module according to actual needs, without further limitations.

[0040] Optionally, the door has an opening and closing side along the opening direction away from the body assembly 2. When the door is not closed, there is a distance between the opening and closing side and the body assembly 2. The area to be detected includes the area between the opening and closing side and the body assembly 2.

[0041] Optionally, the door has a first side and a second side arranged opposite each other in the vertical direction. When the door is not closed, there is a distance between the first side and the second side and the body assembly 2. The detection area also includes the area between the first side and the body assembly 2, and the area between the second side and the body assembly 2.

[0042] Optionally, to better warn users against hand pinching, the electric door active anti-pinch system also includes an alarm device. The alarm device includes an audible alert and a warning light, and is communicatively connected to the controller 3. With this configuration, the anti-pinch detection device 1 detects an object in the detection area and transmits feedback to the controller 3. The controller 3 then stops the electric door from closing and simultaneously triggers the alarm.

[0043] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
